Example of getaddrinfo() for Servers

• struct addrinfo hints, *res, *ai;

• int s;

• memset(&hints, 0, sizeof(hints));

• hints.ai_family = PF_UNSPEC;

• hints.ai_socktype = SOCK_STREAM;

• hints.ai_protocol = IPPROTO_TCP;

• hints.ai_flags = AI_PASSIVE;

• gai = getaddrinfo(name, service, &hints, &res);

• if (gai) {

• printf("getaddrinfo failed: %s\n", gai_strerror(gai));

• return NULL;

• }
